Surface mount counter flashing system

Abstract

A surface mounted counter flashing system and method is provided for securing and sealing a free end of a roofing material to a wall. A compression plate secures and compressingly seals the free end of a roofing material against the wall surface. The top end of the compression plate defines a first sealing trough for receiving a sealing material. The bottom end of the compression plate includes locking portion for attachment to a counter flashing. The counter flashing includes a mounting surface which is mounted to the wall above compression plate. A covering surface extends out from the mounting surface and encloses the compression plate protecting it from exposure to weather. A locking member is provided on the covering surface which connects and attaches to the compression plate, thus, securing the counter flashing. The top end of the counter flashing defines a second sealing trough for receiving the sealing material. Adjacent counter flashings are installed end-to-end leaving a gap therebetween. A splice plate is attached to the adjacent counter flashings at the second sealing trough and covers the gap. The gap and splice plate allow for movement of the counter flashings. The present invention provides for easy assembly and disassembly of the components and provides for a long lasting seal.

We claim: 
     
       1. A roof counter flashing system, the system comprising: a compression plate having a body which is attached to a roofing material and a vertical wall and forming a compression seal against the roofing material, the body including a first end and a second end where the first end is positioned above the second end on the vertical wall;   a first sealing trough defined between the first end of the compression plate and the vertical wall for receiving a sealing material;   a counter flashing comprising: a mounting portion attached to the vertical wall above the compression plate forming a compression seal against the vertical wall;   a covering portion which extends from the mounting portion and covers the compression plate, the covering portion including a locking member for locking the covering portion to the second end of the compression plate; and   a mounting edge extending from a top end of the mounting portion;     a second sealing trough formed between the mounting edge and the vertical wall for receiving a sealing material which prohibits fluid from flowing between the mounting portion and the vertical wall; and   a splice plate for covering a portion of the counter flashing, the splice plate having a first end attached to the mounting edge of the counter flashing and a second end attached to the covering portion.   
     
     
       2. The roof counter flashing system as set forth in claim 1 further including: a plurality of compression plates attached to the wall in an adjacent end-to-end relationship; and   a plurality of counter flashings attached to the wall in an adjacent end-to-end relationship and defining a gap between adjacent counter flashings such that the splice plate is attached to adjacent counter flashings to cover the gap.   
     
     
       3. The roof counter flashing system as set forth in claim 1 wherein the counter flashing further includes a connecting lip extending from the covering portion such that the second end of the splice plate attaches to the connecting lip. 
     
     
       4. The roof counter flashing system as set forth in claim 1 wherein the splice plate is slideable along the counter flashing allowing movement by the counter flashing. 
     
     
       5. The roof counter flashing system as set forth in claim 1 wherein the splice plate includes a geometry that substantially matches a geometry of the counter flashing. 
     
     
       6. The roof counter flashing system as set forth in claim 1 wherein the locking member is formed to attach around the second end of the compression plate. 
     
     
       7. A surface mount counter flashing system, the system comprising: a compression plate for attachment to a wall surface and compressingly sealing a roofing material against the wall surface; and   a counter flashing having a mounting portion attached to the vertical wall above the compression plate forming a compression seal against the vertical wall and a free surface extending from the mounting portion and enclosing the compression plate to restrict exposure of the compression plate to weather, the free surface being connectable to the compression plate to secure the free surface; and   a mounting edge extending from a top end of the mounting portion;   a splice plate for covering a portion of the counter flashing, the splice plate having a first end attached to the mounting edge of the counter flashing and a second end attached to the free surface.   
     
     
       8. The surface mount flashing system as set forth in claim 7 further including: a second counter flashing for attachment to the wall surface adjacent and end-to-end with the counter flashing such that a gap is defined therebetween; and   a splice plate being attached to both the counter flashing and second counter flashing wherein the splice plate covers the gap.   
     
     
       9. The surface mount flashing system as set forth in claim 8 further including a trough edge extending out from the attaching surface of the counter flashing, and the splice plate includes a top end connectable to the trough edge and a bottom end connectable to the free surface of the counter flashing to secure the splice plate to the counter flashing. 
     
     
       10. The surface mount flashing system as set forth in claim 9 wherein the trough edge forms a trough between the wall for receiving a sealing material to prevent fluid from entering between the counter flashing and the wall. 
     
     
       11. The surface mount flashing system as set forth in claim 7 wherein the free surface includes a locking member for connecting to the compression plate, the locking member having a generally hook shape which attaches to the compression plate. 
     
     
       12. The surface mount flashing system as set forth in claim 7 wherein the compression plate further includes a first end extending away from the wall to define a compression plate trough for receiving a sealing material to prevent fluid from entering between the compression plate and the wall. 
     
     
       13. The surface mount flashing system as set forth in claim 12 wherein the compression plate further includes a second end opposite from the first end which forms a locking portion for securing the free surface of the counter flashing. 
     
     
       14. The surface mount flashing system as set forth in claim 13 wherein the counter flashing further includes a mounting edge extending out from the attaching surface and away from the wall which defines a flashing trough for receiving a sealing material to prevent fluid from entering between the counter flashing and the wall. 
     
     
       15. A process comprising the steps of: attaching a compression plate to a roofing material and a wall, the compression plate having a first edge and a locking edge, the first edge defining a first trough between the wall;   filling the first trough with a sealing material;   providing a counter flashing having a mounting surface and a covering surface extending therefrom;   attaching the mounting surface of the counter flashing to the wall above the compression plate forming a compression seal against the wall; such that the covering surface encloses the compression plate, the mounting surface including a trough edge extending out therefrom defining a second trough between the wall;   securing the covering surface to the locking edge of the compression plate; and   filling the second trough with a sealing material; and   attaching a second counter flashing to the wall in an end-to-end relationship with the counter flashing such that a gap is defined between ends; and   attaching a moveable splice plate between the second trough edge and the covering surface overlapping both of the adjacent counter flashing such that the gap is covered by the splice plate.
